BACKGROUND OF THE INVENTION

1. Field of the Invention

Embodiments of the invention described herein pertain to the field of law enforcement. More particularly, but not by way of limitation, one or more embodiments of the invention enable a platform for preservation of a crime scene.

2. Description of the Related Art

Previous methods that are used to support the preservation of crime scenes include generic “DO NOT CROSS” barrier tape used to cordon off the general area of interest, while this does pose a simple barrier it can be bypassed by walking under or around the taped off area.

Other methods and apparatuses used to prevent the disturbance of a crime scene include disposable shoe coverings, while these minimally prevent external debris from being introduced into the crime scene, shoe coverings can allow the possibility of cross contamination of evidence from one area to another as an investigator moves around the crime scene.

To overcome the problems and limitations described above there is a need for an apparatus and methods that ensures a physical barrier between the investigator and any crime scene evidence that cannot be bypassed and will keep the investigators above the area of investigation and will ensure that cross contamination of the crime scene is minimized.

BRIEF SUMMARY OF THE INVENTION

An apparatus and method for preservation of a crime scene is provided. One or more embodiments of the present invention is a portable and modular platform system with foot pegs configured to be laid out over a crime scene, e.g. by Law enforcement personnel, thus reducing the chance of cross contamination of forensic evidence during the course of a crime scene investigation. During the investigation of a crime scene, the platform may be laid out by installing the tubular legs to the underside of the platform to the desired height that will allow the platform to clear any debris or items that are to be considered part of the crime scene. The tubular legs (or foot pegs) may be telescopic to allow for adaptation to any crime scene. The foot pegs are configured to have minimal footprint on the crime scene.
